MINING-DIAOHINE TOOL.

Application filed June 15, 1925. Serial No. 116,115.

This invention relates to mining machine tools and more particularly to a combined conveyer flight and cutting tool, and has for its object the provision of a novel form of tool adapted to be secured to and propelled by a single chain and to both undercut and convey the material being mined.

Heretofore mining machines have been constructed with a. cutter chain having cutiter hits secured thereto and a s r ate conveyerchain having conveyer flights secured theii'eto for conveying away the mined material, therefore necessitating two separate chain mounting and drive mechanisms.

1 The present invention eliminates the use of one chain, its mountings and drive mechanism, thereby materially reducing the cost of manufacture and simplifying the machine construction. 1

Another and important object of the pres ent invention is to provide a cutting tool or bit mounting Which may be bodily adjustable to direct the bits at various angles from a horizontal plane, thereby eliminating the 5 necessity of separately adjusting each of the several picks.

In the drawings:

Figure 1 is a plan view of a section of cutter chain having my combined coiiveyer 30 flight and cutting tools mounted thereon.

' Figure ,2 is an enlarged side elevation,

and Figure 3 is a plan of the forward end of the combined conveyer flightand cutting tools of Figure 1.

Figure 1 is an enlarged side elevation, and Figure 5 is a plan of the forward end of slightly modified construction of conveyer flight and cutting tool. I

Figure 6' is an enlarged side elevation, and Figure 7 is a plan of the forward end ofa second modified construction of conveyer flight and cutting tool. i

Referring more particularly to the drawings, the letter A designates the tool or'cut ter chain which may be of standard design and construction and the letter B designates the combined conveyer flight and cutting tools as a Whole Which are pivotally mounted on the chain as at 2.

Each of the combined conveyer flight and cutting tools B comprises an elongated body portion or flight-bar 3, Which has its free end thickened vertically and shaped to receive a cutting tool-head 1 in Which cutting bits 5 are removably mounted.

Each of the tools B of Figures 1 to 3 is providedv atits free end ith an upwardly and forwardly projecting tongue ,6 Which has its 'side faces serrated as at 6? andis provided With a centrally arranged horizontal aperture 7. The toolhead 1 of Figures 1 to 3' is composed of lJWO cooperating blocks 8 and 9 liichhave their abutting faces relived to fit around the tongue and are apertured at 10 to correspond with the aperture 7. The side faces of the relieved portions of the blocks are serrated as at 12, to intermesh With the serrations 6? on the tongue 6. A bolt 13 is passe-d through the apertures 7 and 10 and provided With a nut 14 so that the the blocks .8 and 9 maybe rocked or pivoted about the bolt 13 and locked in adjusted position by screwing home the nut 14, thus forcing the serrations 6? and 12to intermesh.

The abutting faces of the blocks 8 and 9 are further relieved to form tool or cutter bit receiving recesses 15' and 16, and are apertured to receive bolt 17 adjacent their forward ends adapted to clamp "the blocks 8 and 9 against the bit'shanks.

In the construction of Figures 4 and 5 the tool B is provided with pair of upwardly and forwardly projecting spaced ears 19 Which are apertured horizontally to permit the bolt 20 to pass theret'hrough. Thefltoolhead 4 of this construction is composed of a single block having a tongue 21 at its rear end adapted to fit between the ears 19 and provided with an elongated hole 22 through Which the bolt 20 is passed. 'The rear fa e of the head at each side of the tongue is provided With a plurality of serrations 23 adapted to be intermeshed With cooperating serrations 2 1 on the ears 19 topreve-nt rotation of the head about the bolt 20. The elongated ho1e'22 Will permit the head 4.- to be moved or reciprocated to unmesh the serrations when the nut on the bolt 20 is loosened so thatjthe head may be rotated about the horizontal'axis of the bolt. After the head has been adjusted it Will be moved rearwardly relative to the bolt 20 and ears 19 and locked imposition by tightening the nut of the bolt 20. 1

The head 4 of this construction is provided With a pair of sockets or recesses 15 in Which the cutting bits 5 are mounted and locked by set-screws 25.

In the construction of Figures 6 and 7 the tool B is provided with a pair of upwardly and forwardly projecting spaced ears 26 which are apertured horizontally to permit the bolt 27 to pass therethrough. The toolhead i of this construction is composed of a single block having a tongue 28 at its rear end adapted to fit between the ears 26, and provided with a hole 30 through which the bolt 27 is passed. The ears 26 and the forward end of the bar portion 3 of the tool are slotted as at 31, to receive a key 32 which has its forward face serrated as at 33, which serrations are adapted to mesh with corresponding serrations 34. in the rear face of the tongue 2.

lhe head i of this construction is provided with a pair of sockets or recesses in which the cutting bits 5 are mounted. The bits 5 being locked in position by setscrews 35.

In each of the several constructions or embodiments of my invention, the head 4 is adjustable about a horizontal axis relative to the bar portion 3 of the tool, so as to cut a kerf up or down without changing the position of the cutter bits in the head.

In the construction of Figures l to 3, in order to adjust the position oi the head 4, the nut 14 on the bolt 13 is loosened to permit the unmeshing ot the serrations 6* and 12, and the head i. is then tree to i'nove aboijit the horizontal axis of the bolt 13 relative to the bar or flight portion 3, and when the adjustment is completed the nut la is again screwed home on the bolt 13 to lock the serrations 6 and 12 in mesh.

in the construction 01? Figures 4 and 5, in order to adjust the position of the head 4, the nut on the bolt is loosened sutliciently to permit the longitudinal reciprocation of the head i relative to the bar 3 and bolt 20 so as to disengage the serrations 21 and 23. The head is then rotated about the horizontal axis of the bolt 20 and then shifted or reciprocated rearwardly to again mesh the serrations 21 and 23, and the nut on the bolt 20 tightened to lock the head 4 and bar 3 against relative longitudinal movement. I

in the construction of Figures 6 and 7 in order to adjust the head i, the nut on the bolt 27 is loosened and the key 32 is withdrawn so as to permit iree rotation 01" the head 4% about the horizontal axis 01' the bolt 27 relative to the flight or bar portion 3. After the head 4; is adjusted the key is again inserted in the slot 31 and the nut on the bolt 27 tightened to lock the head t against movement.

While I have shown and described certain specific embodiments of my invention, it will be expressly understood that I do not wish to be limited thereto since various modifications may be made without departing from the scope of my invention defined in the appended claims.

I claim:

1. A combined con'veyer flight and cutting tool for mining and loading machines comprising an elongated flight-bar, and a cutting tool-head removably mounted on one end of and adjustable about a horizontal axis leltltlK-l to said-flight-bar.

3. A combined conveyer flight and cutting tool for mining and loading machines comprising an elongated flight-bar, a cutting tool-hcad pivotally mounted on one end of and adjustable about a horizontal axis relative to said flightbar, and means for locking said head in various adjusted positions.

4. The combination wlth a cutter chain of a mining machine, oi? a plurality of con1- bined conveyer flight and cutting tools pivotally secured at spaced intervals to said chain, each of said conveyer flight and cutting tools comprising an elongated flightbar, a cutting tool-head removably mounted on one end of and adjustable about a horizontal axis relative to said flight-bar, said cutting tool-heads having openings therein for the reception of cutting bits, and means for securing said. bits in position.
